1. Fix for elog(ERROR, "EvalPlanQual: t_xmin is uncommitted ?!")
and possibly for other cases too:
DO NOT cache status of transaction in unknown state
(i.e. non-committed and non-aborted ones)
Example:
T1 reads row updated/inserted by running T2 and cache T2 status.
T2 commits.
Now T1 reads a row updated by T2 and with HEAP_XMAX_COMMITTED
in t_infomask (so cached T2 status is not changed).
Now T1 EvalPlanQual gets updated row version without HEAP_XMIN_COMMITTED
-> TransactionIdDidCommit(t_xmin) and TransactionIdDidAbort(t_xmin)
return FALSE and T2 decides that t_xmin is not committed and gets
ERROR above.
It's too late to find more smart way to handle such cases and so
I just changed xact status caching and got rid TransactionIdFlushCache()
from code.
Changed: transam.c, xact.c, lmgr.c and transam.h - last three
just because of TransactionIdFlushCache() is removed.
2. heapam.c:
T1 marked a row for update. T2 waits for T1 commit/abort.
T1 commits. T3 updates the row before T2 locks row page.
Now T2 sees that new row t_xmax is different from xact id (T1)
T2 was waiting for. Old code did Assert here. New one goes to
HeapTupleSatisfiesUpdate. Obvious changes too.
3. Added Assert to vacuum.c
4. bufmgr.c: break
Assert(buf->r_locks == 0 && !buf->ri_lock)
into two Asserts.

Reset evaluation plan tuple table next free slot counter to 0

tuple slots very soon, though slots are freed by ExecEndNode

We didn't see this problem before because of

TupleTable tupleTable = ExecCreateTupleTable(nSlots + 10);
/* why add ten? - jolly */

3 slots and so it was possible to re-use evaluation plan
3 additional times and didn't get

Clean up uninitialized-variable warning from egcs.
(Curious that gcc doesn't complain about this code...).

egcs thinks omitting the return type in a function declaration
is poor coding style. I agree.

Replace static rcsid[] strings by IDENTIFICATION comments in
file headers, to conform to established Postgres coding style and avoid
warnings from gcc.

configure.in forgot to do AC_LANG_C to reselect C-based tests
after checking for presence of C++ compiler. Odd we hadn't seen any
reports of problems before...

Turns out that configure's test for HPUXMATHLIB didn't work
when used with egcs --- now it does.

1. Run all pg_dump queries in single serializable transaction.
2. Get rid of locking when updating statistics in vacuum.
3. Use QuerySnapshot in COPY TO and call SetQuerySnashot
in main tcop loop before FETCH and COPY TO.
